IMPROVEMENT IN WHIFFLETREES.

Specification forming part of Letters Patent No. 185,009, dated December 5, 1876; application filed April 10, 1876. I

E To all whom it may conceww.

Be it known that I, AARON BURR ALLEN,

. of Barry, in the county of Pike and State of 'shows 'an enlarged view of one end of the double-tree with the parts detached.

Fig. 3 is an end view of the parts shown in Fig. 2. Fig. 4 shows the application of my invention to a trace or side strap.

The object of my invention is to overcome the danger and inconvenience of traces coming unfastened while in use, and also to make it convenient in taking single-trees from double-trees and applying them to plows, harrows, &c.; and it consists in the novel construction and arrangement of the attaching and detaching device or look, as hereinafter explained.

In the drawing, the letter A represents the double-tree,'and B the single-trees, which are connected by a lock, H, composed of the parts E, O, and D. G is the slotted barrel of the lock, which is fastened to the double-tree by sawing a slit in the Wood and driving it on, the flange E being already turned down. D,

the bolt of the lock, is then slipped in the barrel by raising it up till the shank m of bolt D passes into and through the longitudinal slot d into the rightangled slot 0 in the barrel. (See Fig. 2.) The bolt D is fastened to the single-trees by a common staple, but on traces with an S-hook, which is hooked on any trace and then closed up, when it becomes a part of the trace. H represents the lock as unfastened. F, K, and G show the bolt of the lock attached to a trace.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

The whiffletree-lock H, composed of the barrel 0, provided with the flange E, and having the slots d and c, in combination with thebolt D, provided with the shank m, all constructed to operate-substantially as and for thepurposeset forth.
